FFX on PC?

Is it possible to play this on the PC? I've read little tidbits around the internet of something called PCSX2 or something like that, but how does it actually work? Is it legal? Does it look as good as it does on PS2? Does it require a strong PC? and so on.

Thanks in advance for any replies!

It can be done, yes. But it's not legal, and we're not allowed to discuss it here.
